A set of glasses with an electronic heads up ruler for hand free measuring. Like fighter piolots use except for carpenters and welders and taylors. Worn like reading glasses. Close one eye, look through glasses and a heads up ruler appears that electronically measures distance to object focused
upon with a tiny laser and atomatically adjust the scale on the heads up display.

Someone recently proposed a laser projected ruler. Same end result. |

That's going to be an expensive pair of glasses.
Don't measure anyone's iris, please. |

Well, if it's any good it'll have several scales available, even the semi-useful metric scales. |
